Back in saddle I yearn to climb down (5)
I believe the answer is:
yield
'climb down' is the definition.
'back in saddle i yearn' is the wordplay.
'back' says the letters should be written backwards.
'in' says the answer is hidden in the clue.
'dleiy' is hidden within 'saddle i yearn'.
'dleiy' back-to-front is 'YIELD'.
'to' acts as a link.
(Other definitions for yield that I've seen before include "Make a submission" , "admit defeat" , "Abandon" , "Surrenders or bears as a crop" , "Amount produced" .)
